New: SST Validation

Results are now available from a new sea surface temperature (SST) validation system providing ground-truth of satellite-borne measurements via comparisons with coincident in situ temperature measurements. Successful match-ups are compiled into one global file per date for each different sensor, and made available via a simple web-based search engine and API. More info. Produced in collaboration with the SST group at the Rosenstiel School of Marine and Atmospheric Science at the University of Miami.


A validation update

Recently released AERONET-OC data (Version 2, level 2.0) were processed for SeaBASS validation. These data were also used to create SeaBASS's first VIIRS-JPSS1 validation results.


Metadata Header Updates

Several new metadata headers have been created to make it easier to interpret useful information without users needing to manually parse external documents. These new headers are optional but recommended from now on:

  • instrument_model (e.g., PRR-800)
  • instrument_manufacturer (e.g., Biospherical_Instruments_Inc.)
  • calibration_date (e.g., 20190230)
